Things to know before buying Pollution masks

Although, air is mostly invisible even to the naked eye, it is filled with tiny particles such as smoke, allergens, germs, chemicals, bacteria, viruses and other small particles. All these particles are hazardous to our health as we inhale them on daily basis. Thus, we require filter masks to protect ourselves.


Filter masks are not only useful in protecting us from Covid-19. They are also useful in protecting us from the hazardous particles present in air we breathe. But are we using the right filter mask?


To answer this question, we need to know about the mask required for both air filtration and for Covid-19.


PM stands for particulate matter which is a mixture of solid and liquid particles that are suspended in the air and are categorized as coarse, fine and ultrafine. Coarse particles have a diameter of 2.5 micrometers to 10 micrometers which is relatively 25 to 100 times thinner than a human hair. These particles are heavy and thus settle down easily. Dust and pollens are examples of coarse particles.


PM 2.5 refers to particles that have diameter less than 2.5 micrometers which is 100 times relatively thinner than a human hair. These particles remain suspended in the air for long duration as these are light in weight and don’t settle down. These particles are formed as a result of burning of fuel, automobile exhaust, burning of garbage and landfill, processing and melting of metals as well as chemical reactions that form in the air.

Particulate matter is extremely hazardous for the human health. The smaller the particles size, the greater the risk. Particles less than 10 micrometers in diameter pose the greatest risk as they easily get into your lungs and even bloodstream. Both lungs and heart are greatly affected by inhalation of such particles. Some of the major health concerns posed by the particle pollution are:


1. Heart and lung disease.


2. Non-fatal heart attacks.


3. Irregular heartbeat.


4. Aggravated asthma or bronchitis.


5. Decreased lung function.


6. Increase in respiratory symptoms like irritation of the airways, coughing or difficulty in breathing.


Some of the major environmental concerns posed by the particle pollution are:


1. Visibility impairment.


2. Making lakes and streams acidic.


3.Depleting nutrients in the soil.


4. Damaging crops and forests.


5. Affecting the diversity of ecosystems.


6. Contributing to acid rain effect.


PM 2.5 filter masks are made from the same advanced material as respirators N99 and KN95 and carries an added carbon filter layer. A PM 2.5 filter offers a high degree of filtration from particulates and aerosols. This filter is not only capable of filtering particles of 2.5 microns size but much smaller particles. Combined with layers of cotton, it not only provides comfort but a less inhalation resistance.


The ‘Raksha 4 Ply Anti-Pollution Mask’ of brand 3Se, a subsidiary of KeePharma, is the 2-in-1 mask that provides protection from Covid-19 and pollution at the same time. It is effective against droplets, particles, dust, smog, pollutants, and contaminants and provides 99% bacteria filtration efficiency.


Its key features are:


1. Active carbon filter for superior filtration against contaminants and impurities.


2. Concealed adjustable nose clip to ensure a perfect seal, fit, and comfort.


3. Superior construction - thermally sealed seams and ear loops.


4. Single-use disposable.


5. Latex and silicone-free.


6. Skin-friendly material.


7. Lightweight and comfortable - designed to reduce user fatigue. So, use Raksha 4-ply anti-pollution mask and get ‘Double-Suraksha.’
